processes of gypsum grinding calcining

  • Grinding and calcining of gypsum with Pfeiffer grinding plants

    One option is direct calcining in a Pfeiffer vertical roller mill of the type MPS-GC (Fig. 2). In this process, the gypsum is dried and ground to the required fineness of the plaster in the mill. Thanks to the relatively high temperature level in the gypsum calcining mill, the gypsum is simultaneously calcined.

  • Grinding and calcining of gypsum with Pfeiffer grinding

    Nov 01, 2014· When gypsum is calcined in an atmosphere sat­urated with water vapour at an overpressure of several bars, a-hemihydrate is formed (Fig. 1). The outstanding feature of this plaster is a relatively regular crystal form.

  • Gypsum Calcining

    Gypsum is the crystalline chemical compound CaSO4·2H2O. A close chemical relation and frequently occurring with Gypsum is Anhydrite which is CaSO4. Gypsun has wide commercial use because relatively simple heat processing reduces it to Plaster of Paris. While Anhydrite can be converted to Gypsum and thence to Plaster of Paris, the procedure is not simple and is quite costly. Anhydrite

  • Gypsum Calcination Innogyps

    Calcination is the practice of dehydrating gypsum into plaster or stucco through a batch or continuous process which includes heating the gypsum to evaporate the crystalline water. Typically, free water is removed in an initial process at approximately 45℃ and crystalline bound water is removed in a second process at 120-180℃.
